Filed: 1965-10-01
Abstract: 1,107,020. Multiplex pulse code signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 1 Oct., 1965 [5 Oct., 1964], No. 41726/65. Heading H4L. In a multiplex digital transmission system a plurality of streams of information bits are arranged in sets, each set consisting of a corresponding bit from each stream, the sets being convreted into amplitude quantized pulses in accordance with a predetermined code in correspondence with the binary status of the bits of each set thereby to form a single train of pulses of quantized amplitude to effect transmission over a channel of limited bandwidth. As shown, at the West terminal a clock 6 provides clock pulses for the transmitter 4 and receiver 5. Input signals consisting of speech 9, Telex 10 and, data 11 are fed to a switching circuit 13 and via appropriate Vocoders, buffers &c. to a time division multiplexor 15 producing three streams A, B and C, Fig. 2 (not shown), of T.D.M. bits. The three streams are supplied to a coder 19 in which the time-corresponding bits of the streams are treated as a code group representing a numerical value in, for example, the simple binary code in which the bit values are 4, 2 and 1 unite for streams A, B and C, respectively. These code groups are converted into a corresponding one of the eight possible quantized amplitudes, which appropriately phase-shift a carrier from source 23 via modulator 22, the phase-shifted carrier being transmitted over cable 3 to the East terminal 2. The incoming quantized amplitude pulse train is supplied via a phase detector 25 to a decoder 27 which translates the amplitude modulated pulses back into the three streams of bits which are fed via a distributer 29 to the appropriate utilization devices 32.

Abstract: 1,159,695. Griseofulvin. BIOCHEMIE KUNDL G.m.b.H. 23 Sept., 1966 [24 Sept., 1965], No. 42549/66. Heading C2A. Griseofulvin is produced by cultivating a griseofulvin-forming fungus in a nutrient solution containing 15 to 25% sucrose and assimilable sources of nitrogen and inorganic salts, by surface culture technique at 25‹ to 30‹ C. in a stream of moist air which is introduced in such a manner that the rapid formation of a coherent fungus carpet is not disturbed, the cultivation being effected under sterile conditions for at least the first three days. The fermentation is effected in a fermentation vessel containing fermentation trays 6 interconnected by means of overflow devices 7, and having an aerating device 2 extending into the interior of the cover and having outlets 3 so positioned as to direct the stream of air against the interior cover wall of the fermenter. An impingement plate 4 situated below the aerating device 2 but above the fermentation trays 6 deflects the air rebounding from the cover down the sides of the fermentation vessel so that a satisfactory distribution of air over the fermentation trays 6 is obtained. Near the end of the cultivation period the moisture content of the air passed through is reduced so that a substantially dry mycelial blanket is produced. After three days, the trays may be removed from the fermenter and placed in a moist room at 28‹ C. and allowed to ferment for 2 to 3 weeks under non- sterile conditions. Griseofulvin may be isolated from the solid fungus blanket in a conventional manner by extraction with a solvent, e.g. dimethyl formamide. Suitable griseofulvinproducing micro-organisms are Penicillium griseofulvum, penicillium urticae, Penicillium nigricans and mutants of Penicillium urticae NRRL 989, e.g. NRRL 3316 and NRRL 3317.

Abstract: 1,155,410. Self-levelling lifting devices. W. A. M. POMPE. 23 Sept., 1966 [14 May, 1966; 12 Aug., 1966], No. 42711/66. Heading B8H. When a load having a centre of gravity to the left of a pivot 8, Fig. 1, is raised by a selflevelling lifting beam 1 the beam will turn anticlockwise and an upper spring 26 will be compressed by an arm 24b. After a short time-delay, fluid will be pumped from a ram 10 by the weight of the load into the left-hand side of a ram 9, thus moving trolleys 4a ,4b, from which the load is suspended, to the right to effect a balance. As the load is raised a spring 18 is tensioned. This acts as an energy accumulator for returning the device to its original condition after the load has been set down. As shown in Fig. 2 a beam 41 is suspended from a pivot 48 by rams 44, 45. If the centre of gravity of the load is to the left of the pivot 48 the beam will rotate anticlockwise and an arm 52 will turn clockwise moving a regulating slide 56 downwards. This allows fluid to flow from the ram 45 to a tank thus causing extension of the ram. As a result, the pivot 48 moves upwards and to the left until equilibrium is reached. Springs 59 store the energy for returning the device to its original condition. Fig. 3 shows an arrangement in which a beam 11 is supported by a pair of rams 2, 3 and a chain 14 which passes round a sprocket 15. If fluid is forced out from one of the rams the piston-rod will descend and the sprocket 15 will be rotated by the chain 14. This will cause sprockets 17 to rotate and drive trolleys 10, which connect the beam to the rams 2, 3, to either the right or the left by means of chains 18. The flow of fluid from rams 2, 3, Fig. 3b, is controlled by valves 27 which are opened when floats 29 move downwards. A flow of fluid occurs between float chambers 35, 36 through a pipe 39 when the beam is tilted.
